Obesity is considered the pandemic of this century. With the popularization of bariatric surgery due to its effectiveness, the number of procedures has significantly increased. One of the most performed surgeries is sleeve gastrectomy (SG). It is a safe procedure that rarely presents complications, with the most common being bleeding or staple line leaks. However, there are other less common complications or those that have been infrequently reported in the literature, such as acute hiatal hernia (AHH), which may require additional surgical intervention if it occurs. As the number of bariatric procedures performed worldwide increases, the likelihood of encountering these low-incidence complications also rises. The few cases reported in the literature describe different surgical techniques for this complication. The objective of this study is to describe the case of a female patient who developed AHH after undergoing SG, which was successfully treated with reduction and omentopexy in Mexico.
